On the feast day for St. Michael & All Angels, Frederick Buechner’s words set a great tone for the day:

Slight-of-hand magic is based on the demonstrable fact that as a rule people see only what they expect to see.  Angels are powerful spirits whom God sends into the world to wish us well.  Since we don’t expect to see them, we don’t.  An angel spreads his glittering wings over us, and we say things like “It was one of those days that made you feel good just to be alive” or “I had a hunch everything was going to turn out all right” or “I don’t know where I ever found the courage.”
